dnsmasq configuration for an exit relay (Debian)
by jpmvtd261＠laposte.net 10 Oct '17

10 Oct '17

Hello, I am looking for instructions on how to configure dnsmasq on a Debian exit relay (in order to cache DNS queries). It looks like this package could introduce vulnerabilities if not handled properly, because it provides more than just local DNS cache. If I had to install it without any advice, I would do this : 1) Install dnsmaq package with the command "aptitude install dnsmask" . 2) Make sure that the first line of the file /etc/resolv.conf is "nameserver 127.0.0.1" (see https://wiki.debian.org/HowTo/dnsmasq#Local_Caching ). 3) Make sure that the file /etc/dnsmasq.conf contains the line "listen-address=127.0.0.1" (to restrict dnsmasq to the local system). 4) Set the cache size to 10000 by adding or editing this line "cache-size=10000" in the file /etc/dnsmasq.conf (as suggested by Igor Mitrofanov here https://lists.torproject.org/pipermail/tor-relays/2017-August/012708.html ). 5) Reboot (is it necessary ?). Does anyone think that this procedure could start a daemon listening on a port of my server ? Or is it safe to do this on my exit relay ? Regards

Re: [tor-relays] Tor exit nodes attacking SSH?

After that check from which ip it was logged in. This probably would be ip of the exit node.

Re: [tor-relays] Feedback wanted: letter to my university's library
by Alison Macrina 08 Oct '17

Hi AJ, Thank you for supporting Tor! I think it's a great idea to try to work with your university library to run a relay. I run the Library Freedom Project which helps libraries understand and use privacy tools (libraryfreedomproject.org) I can give you some advice based on my experience. William Denton: > On 1 October 2017, AJ Jordan wrote: > >> However I've just started college at the University of Rochester, >> which obviously presents a great opportunity to set up a relay on a >> really great network.

William's advice is good. You definitely need to begin by building a relationship with the library. Don't be discouraged by the amount of work this may take; the payoff might end up being a cultural shift wherein the library, university IT, and CS departments all work on this as a project together! You'll want to approach the library by showing that Tor is an excellent way to uphold the values of librarianship, which are privacy, intellectual freedom, and access. Really, be explicit about it; don't assume that they'll just get why you think it matters. Here's something I wrote about intellectual freedom + Tor Browser a while ago and you can borrow the arguments I've made: https://www.scribd.com/document/272919852/Alison-Macrina-The-Tor-Browser-an… As William said, libraries are mostly risk-averse, so you also need to be ready to answer their questions about legal and technical concerns. LFP has collected some resources to help with all of that here: https://github.com/LibraryFreedom/tor-exit-package/blob/master/resources.md. Before you email the university librarian, I'd start by talking to some of the regular academic librarians about your ideas and gauge their responses. Ask them if they've heard of the Library Freedom Project and feel free to send them any of our resources. See if they think the administration would be receptive to you offering a presentation about Tor to library staff (even better if you can make it open to students and faculty, too, because that can get you more support). You are welcome to adapt these slides for that presentation: https://libraryfreedomproject.org/allabouttor/. Make sure to show them this academic library that has used their Tor relay as a teaching tool for students: https://boingboing.net/2016/03/16/first-ever-tor-node-in-a-canad.html. LFP is fairly well known and respected in libraries and so if it can be beneficial to involve me further, I'm happy to assist! Alison

About relay size
by IPonU 08 Oct '17

08 Oct '17

Hi Tor list, I'm already running a small exit node (100Mbps bandwidth) and I'm ready to spend more money on it, so have a question for you guys : Is it better if I run other small ones (100Mbps too) or only 1 big exit relay (1 Gbps) ? What's best for the network stability/security ? Thanks a lot IPonU

anonymaid tor relays: MyFamily configuration
by nusenu 07 Oct '17

07 Oct '17

Hello anonymaid Relay Operator, thanks for running relays. Since you recently added more relays you are now in a position that can potentially harm tor users if you do not set MyFamily (torrc) on all your relays. Please have a look at you MyFamily configuration. https://nusenu.github.io/OrNetStats/endtoend-correlation-groups some more background: https://hackernoon.com/some-tor-relays-you-might-want-to-avoid-5901597ad821 Let us know if you need help with configuring MyFamily. thanks, nusenu -- https://mastodon.social/@nusenu twitter: @nusenu_

Blocking outbound 22 or no?
by AMuse 06 Oct '17

06 Oct '17

Hi all! I'm getting a number of ISP Abuse complaints around outbound ssh brute-forcing from our exit relay. I'm personally of the opinion that people should run fail2ban (or equiv) and get on with life and I generally ignore the complaints - but wondered, what are other operators doing? Is anyone exit-policy blocking outbound 22 to make the internet a kinder place? Is anyone refusing to on principle?
